Answer:

Step-by-step explanation:

Given that:

To evaluate the expression, we must simply substitute the given value of 
, which is 
, for 
:

Multiply:

Subtract:

-
To check your work, simply set the given expression equal to our solution, 
:

Add 
 to both sides of the equation:

Divide both sides of the equation by the coefficient of 
, which is 
:

Since it matches the given value of 
, our solution is correct!
